Hello, thank you very much for your patience in explaining.
But I have one more question I'd like to ask you
Why does Shift and Ctrl work when you select an object by click, but not when you select an object by box?
Also, when the box selects an object, the words SHIFT and CTRL appear in the upper left corner of the screen.

Thank you for your answer
I know this clock menu function
But I think Shift and Ctrl are more convenient
And when I select the second point in the box, when I hold down these two keys, these two words also appear in the top left of the screen, but they don't work, which I feel a little sad about.
